On the Paratypes and Distribution of \u3cem\u3eHemipeplus quadricollis\u3c/em\u3e Pollock, 1999 (Coleoptera: Mycteridae: Hemipeplinae): Does It Occur in Peru?
Get PDFHemipeplus quadricollis Pollock, 1999 (Coleoptera: Mycteridae: Hemipeplinae), was originally described from Rondonia State, Brazil, as its type locality, with 10 paratypes: eight from Brazil (Rondonia State) and two from Peru (Madre de Dios and Loreto departments). However, one of the paratypes from Peru (Madre de Dios) was later identified as a cryptic species, Hemipeplus pseudoquadricollis KC and Pollock, 2025. This raises questions about the single remaining paratype from Peru—whether the species truly occurs in Peru—and how many of the paratypes of H. quadricollis are actually H. quadricollis. In this study, all seven remaining paratypes of H. quadricollis that were not studied by KC and Pollock (2025) were examined based on morphological characters to address these two questions. It was determined that the remaining paratype of H. quadricollis from Peru, collected in Loreto Department, is H. quadricollis, thus confirming its presence in Peru, while three out of the 10 paratypes of H. quadricollis are H. pseudoquadricollis
Water Holding Capacity of Soil and Resilience to Drought
Get PDFFor the past two years, I have been involved in an NSF-funded research project titled “RII Track-2 FEC: Supporting Rural Livelihoods in the Water-Stressed Central High Plains.” The overarching goal of this project is to evaluate the potential of microbials and biochar to enhance soil water holding capacity (hereafter, WHC), thereby improving drought resilience in crop production and reducing irrigation demand to slow aquifer depletion. Visit the project website for more details. A key component of this research is assessing the economic viability of these interventions, a task for which I am responsible.
To understand the economic benefits of increasing soil WHC, I estimated its impact on the resilience of crop yields during droughts using county-level yield and soil data. In this blog post, I present preliminary results from this analysis

Effect of Feeding Two Different Feed Additives (Optipartum C+ and Prime Force) on Finishing Cattle Performance and Carcass Characteristics
Get PDFSummary with Implications
A feedlot study was conducted to evaluate the effects of adding two different natural feed additives, Prime Force and Optipartum C+, on finishing cattle performance and carcass characteristics. Treatments were applied as a 2×2 factorial that included a control diet with no additive; a diet containing Prime Force; a diet containing Optipartum C+; and a diet containing both Prime Force and Optipartum C+ combined. Treatment diets were fed the last 67 d prior to slaughter as designed. Cattle fed Prime Force had greater live final body weight, carcass weight, intake, and average daily gain compared to cattle not fed Prime Force but due to increased intake and gain, no impact was observed on feed conversion. Feeding Optipartum C+ resulted in increased hot carcass weight and carcass-adjusted final BW as well as greater ADG which led to a small improvement in feed conversion compared to cattle fed no Optipartum C+. These data suggest that adding Prime Force to finishing diets improved gain and hot carcass weight, while feeding Optipartum C+ improved gain without increasing intake. No interaction suggests combining the two was additive resulting in 24 lb of carcass weight and 42 lb of live weight for the combination treatment compared to no additives
Surveys and Modeling: Using an Existing Survey to Describe and Compare Populations to Better Inform on Groundwater Model Inputs
No full textThe Mississippi River Valley “Alluvial Aquifer” is among the most agriculturally significant aquifers in the United States. However, parts of the aquifer are exceeding sustainable yield as development of the water source continues. Survey research in other aquifers, such as the High Plains (Ogallala) Aquifer, has helped to understand the perceptions and attitudes of irrigators withdrawing from their aquifers. This led to numerous questions: What are the attitudes of irrigators in the Alluvial Aquifer region? How do they compare to irrigators in other regions of the country? Can their intentions be used to generate more accurate inputs when modeling adoption of more efficient irrigation systems?
These questions were addressed through an interdisciplinary approach. An existing survey was identified which collected information on irrigators attitudes and perceptions regarding groundwater. The survey was modified for irrigators in Arkansas who withdraw from the Alluvial Aquifer. Results were then compared to those of the Ogallala Aquifer to identify principle social similarities and differences between the two regions. Finally, results of the survey regarding intention to adopt water efficient irrigation systems were used to generate realistic adoption rates. Those rates were converted to reduced well discharges for the regional groundwater model: MERAS.
Results show that, despite similarities between these regions, the populations should be perceived as distinct agricultural communities with differing perceptions. Further results show that the strongest predictors of farm water management practices were often prior adoption of other practices. Meanwhile, modeling results indicate that savings from both Surge Irrigation and Tailwater Recovery systems ranged from 2.02–8.31 inches per year per reduced discharge cell.
It is therefore recommended that focus should be placed on individuals who have already adopted other practices when promoting new irrigation practices. Assistance to farmers and information sharing should also be increased to financially incentivize adoption. Finally, it is recommended that survey research continue to be used when developing water response models for irrigation efficiency system adoption rates.

Belly Dance in Nebraska: Identity, Social Acceptance, and Perseverance
No full textBelly dance is an art form as well as an often-contested practice due to tensions over dress, terminology and cultural practices within the belly dance community because the dance originated outside the United States. Additionally, there is often a need to prove the legitimacy of the dance to those outside its sphere because it is often stigmatized due to the early association with exotic dancing. Belly dance is inherently geographic, as seen through its places of origin, music and movement styles, global spread, practitioners, and spaces of practice. However, it has not been well-represented in geography, and there is also a lack of research in the Great Plains area of the United States. This qualitative dissertation will explore the cultural/dance identities formed by persons engaging in belly dance in the central Great Plains, specifically the state of Nebraska, to discover what are the reasons Nebraska people choose to belly dance, why Nebraska belly dancers continue to engage in an activity that may, or may not, be stigmatized, and is belly dance in Nebraska welcoming to all bodies, a safe space to “be”?
This study found that belly dancers in Nebraska enter into the dance and stay for similar reasons as those in the literature, that stigma is present in Nebraska, and that the dance appears to be welcoming to all Nebraska people and all bodies. This research adds to the field of Geography by its use of both cultural and feminist geographic methods to focus on belly dance in a specific state of the Great Plains region, by the examination of who is allowed to use the belly dance space, and by the updating of the literature on belly dance and the study of stigma. It also helps to educate Nebraskans and others outside the state about the belly dance community that lives here.

A Phenomenological Study of Rural Immigrants and Their Experiences of Community Leadership
No full textThe turn of the 21st century has seen a new settlement pattern of immigrants bypassing traditional urban gateways and locating to rural spaces instead. Rural immigration presents a unique opportunity to advance the vitality of small towns as the development of communities is best served by a fully networked and integrated community. The purpose of this transcendental phenomenological study was to examine the experiences of rural immigrants with community leadership. Research questions focused on how rural immigrants perceive, identify with, and access their local community leadership. Through one-on-one interviews, 10 participants provided rich qualitative data that were analyzed to yield textural, structural, and composite descriptions (Moustakas, 1994) of the shared phenomenon of community leadership. Findings reveal that rural immigrants experience community leadership as a broad practice of service meant for all members of the community, and not just a select few. This form of leadership as service typically emerged from participants’ lived experiences and personal histories. The experience of community leadership by rural immigrants also involves complexities in representation and challenges in developing immigrant leaders. This study offers significant contributions to theory, research, and practice. Future research should seek to include the voices of immigrants at all stages of arrival or integration into the community to inform more robust and tailored strategies for effective community development.
